Product Description
Product Overview
BWD-01 Water Decoloring Agent is a polycationic flocculating agent formulated with dicyandiamide formaldehyde resin. This liquid solution effectively removes color from industrial wastewater in textile dyeing, paper mills, and dye manufacturing facilities through advanced coagulation technology.
Technical Mechanism
- Positively charged cationic polymer neutralizes negatively charged pollutants
- Forms insoluble complexes for efficient sedimentation and removal
- Enhanced performance when combined with inorganic flocculants like aluminum sulfate, poly-aluminum chloride, or ferric chloride
- Superior color removal for both hydrophobic and hydrophilic dyes including reactive, acid, and disperse dyes
- COD removal rates exceeding 98% with proper application
Application Fields
- Textile dyeing and printing wastewater treatment
- Dyestuffs and pigment manufacturing facilities
- Ink production and paper making mills
- Color removal treatment across multiple industrial sectors
- Retention agent in paper and pulp manufacturing processes
Technical Specifications
| Parameter | Specification |
|---|---|
| Product Name | Dicyandiamide Formaldehyde Resin (BWD-01) |
| Appearance | White or light yellow aqueous solution |
| Solid Content | ≥50% |
| Specific Gravity | ≥1.20 g/ml at 25°C |

Application Guidelines
- Dilute with 40-50 times water before dosing into wastewater
- Adjust pH to 8-10 for optimal decolorization performance
- For high chroma wastewater, combine with polyaluminum chloride (PAC) sequentially
- Add small quantities of anionic polyelectrolyte for enhanced floc formation
- Consult technical personnel for customized treatment solutions
Treatment Case Studies
Case A: Biological Treatment Followed by Chemical Treatment
| Chemical | Dosage | Application Sequence |
|---|---|---|
| BWD-01/03 | 50-80 ppm (raw) | Apply after PAC with 5-10 min contact time |
| Polyaluminum Chloride | 15-20 ppm (solid) | First application with 3-5 min contact time |
| Anionic Polyacrylamide | 1-2 ppm (solid) | Final application |
Optimal performance achieved at pH 7-8, reducing BWD-01 consumption by approximately 20%.
Case B: Direct Chemical Treatment
| Chemical | Dosage |
|---|---|
| BWD-01/03 | 80-100 ppm (raw) |
| Polyaluminum Chloride | 15-30 ppm (solid) |
| Anionic Polyacrylamide | 1-2 ppm (solid) |
pH adjustment to 7-8 recommended for maximum efficiency.
